mean (replaces TMean) The mean function returns the mean of a 1-dimensional array, CImage, or list of numbers. The parameters must contain numbers or strings that can be converted to numbers. This function is similar to the CStat:Mean method but does not require calling new_stats() beforehand to create a CStats object. The meansdev function calculates both the mean and standard deviation of a 1-dimensional array, CImage, or list of numbers. Whereas this function operates on a pure (indexed) array, the slightly slower meann and meansdevn functions caculate the mean value for a general table that may be a multi-dimensional array or contain a mixture of numbers, strings, named keys, and sub-tables. SyntaxnMean = mean( Data )
RemarksThe CImage class supports values ranging from byte to double plus other pixel types. ExamplesThe following script returns the mean and standard deviation of a table containing 1 million random numbers.
The next script returns the mean value for pixels inside a rectangle at the corner of a CImage.
The next example computes the mean value of a list of numbers:
